pubmed:abstractText |
A novel negatively acting factor has been identified and partially purified from HeLa and BJA-B cell extracts by chromatographic fractionation. Addition of this factor to HeLa cell extracts or to a reconstituted HeLa cell transcription system repressed transcriptional activation by a chimeric activator, GAL-TEF-1, containing the activation function of transcriptional enhancer factor-1 (TEF-1). In contrast, this factor did not repress transactivation by the chimeric GAL-VP16 activator. Repression of transactivation by GAL-TEF-1 could be alleviated by the addition of immunopurified HeLa cell TFIID, but not by increased quantities of GAL-TEF-1. These observations suggest that this negatively acting factor represses transactivation by interfering with the function of, or competing for, the TATA-binding protein-associated coactivators which mediate the activity TEF-1.
